Method, device and system for video call

The invention belongs to the technical field of computers and provides a method, device and system for video call. The method comprises the steps of receiving video data and audio data, sent by a local communication device, of an opposite side of conversion; converting the video data into three-dimensional video data when the data type of the video data is marked as two-dimensional video data, displaying and outputting a three-dimensional image corresponding to the three-dimensional video data and a video image acquired by a local camera in the same display device, and outputting audio frequency corresponding to the audio data at the same time, so that three-dimensional immersive video call is realized by means of virtual reality equipment and the existing local communication device and video call experience is improved for users. 本发明适用计算机技术领域，提供了种视频通话方法、装置及系统，所述方法包括：接收本地通信设备发送的通话对端的视频数据和音频数据，当所述视频数据中包含的数据类型标识为二维视频数据标识时，将所述视频数据转换为三维视频数据，在同显示设备中显示输出所述三维视频数据对应的三维立体图像和本地摄像头获取的视频图像，同时输出所述音频数据对应的音频，从而利用虚拟现实设备和现有本地
